Microemulsion light duty liquid cleaning compositions

Abstract

A microemulsion light duty liquid detergent with desirable cleansing properties and mildness to the human skin comprising: a C8-18 ethoxylated alkyl ether sulfate anionic surfactant, a sulfonate anionic surfactant, an alkyl polyglucoside surfactant, and a betaine surfactant and/or amine oxide surfactant, a cosurfactant, a water insoluble hydrocarbon, essential oil or perfume, water and optionally a C8-18 mono or dialkoxylated alkylamide.

What is claimed: 
     
       1. A clear microemulsion light duty liquid cleaning composition which comprises approximately by weight: (a) 2% to 15% of a metal salt of an anionic sulfonate surfactant;   (b) 2% to 15% of an alkali metal salt of a C8-18 ethoxylated alkyl ether sulfate;   (c) 1% to 12% of a betaine surfactant and/or amine oxide surfactant;   (d) 1% to 12% of at least one solubilizing agent;   (e) 1% to 14% of at least one cosurfactant wherein said cosurfactant is selected from the group consisting of polyethylene glycols having a molecular weight of 150 to 1000, polypropylene glycol of the formula HO(CH 3  CHCH 2  O) n  H, wherein n is 2 to 18, mixtures of polyethylene glycol and polypropylene glycol, mono and di C 1  -C 6  alkyl ethers and esters of ethylene glycol and propylene glycol having the formulas of R(X) n  OH and R 1  (X) n  OH, R(X)nOR,R1(X)nOR1 and R1(X)nOR wherein R is a C 1-6  alkyl group, R 1  is a C 2-4  acyl group, X is (OCH 2  CH 2 ) or (OCH 2  CHCH 3 ) and n is from 1 to 4;   (f) 0.5% to 10% of urea;   (g) 1% to 8% of water insoluble unsaturated or saturated organic compound wherein said organic compound is selected from the group consisting of water insoluble hydrocarbons having 4 to 30 carbon atoms containing 0 to 4 different or identical functional groups, water insoluble aromatic hydrocarbons containing 0 to 3 different or identical functional groups, water insoluble heterocyclic compounds containing 0 to 3 different or identical functional groups and water insoluble ethers containing 0 to 3 different or identical functional groups and mixtures thereof;   (h) 1% to 12% of an alkyl polyglucoside surfactant;   (i) 0.8% to 6% of a C8-18 mono or dialkoxylated alkylamide; and   (j) the balance being water.   
     
     
       2. The composition of claim 1, wherein said solubilizing agent is a C2-5 mono, di or polyhydroxy alkanol. 
     
     
       3. The composition of claim 1, wherein said solubilizing agent is selected from the group consisting of isopropanol, ethanol, glycerol, ethyleneglycol, diethyleneglycol and propylene glycol and mixtures thereof. 
     
     
       4. The composition of claim 1, wherein cosurfactant is dipropylene glycol monomethyl ether. 
     
     
       5. The composition of claim 1, wherein said cosurfactant is diethylene glycol monobutyl ether.
